VENTILATED UMBRELLA;

SPECIFICATION forming part of Letters Patent No. 617,415, dated January10,1399.

Application filed Jame 22, 1898. Serial No. 684,152. (No model.)

To allwhiom it maly concern:

Be known that I, MICHAEL ANGELO EATMAN, a citizen of the United States,residingjatfIttabena, in the county of Leflore and State of Mississippi,have inventeda new and useful Ventilator for Umbrellas and Parasols, ofwhich the followingis a specification.

My invention relates to improvements in ventilators for. umbrellas andparasols; and the primary object that I have inview is to provide aconstruction by which a current of air may circulate upwardly throughthe central part of an umbrella or parasol, so as to admit of the escapeof warm air confined within the limits of the umbrella and secure theadmission of cooler air to the structure, thus promoting the comfort ofthe user.

A further object of the invention is to provide an improved ventilatorwhich may be readily closed by hand to exclude driving rain fromentering the umbrella'through said ventilator, and a further object isto simplify the construction and operatively connect the parts of theventilator to the umbella-ribs for the purpose of making the ventilatorfoldable with the umbrella to which it is applied With these ends inview the invention consists in the novel combination and arrangement ofparts of the ventilator in relation to certain elements of the umbrellaor parasol, all as will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustratedthepreferred embodiment thereof in the accompanying drawings, forming apart of this specification ,in which Figure 1 isa sectional elevationwith my improved ventilator applied to an umbrella and. showing theparts in their opened positions. Fig. 2 is an enlarged verticalsectional view through the ventilator with certain parts of the umbrellaand illustrating the slidable ventilator-bands in their closed positionsto exclude rain from entering the umbrella through theventilator. Fig. 3is aview simi: lar to Fig. 2 with the slidable bands opened to permitair to circulate freely from the urnbrella to the ventilator. Fig. 4 isa detail perspective View of one of the ofiset links by which the radialarms of the ventilator may be attached to the umbrella-ribs.

Like numerals of reference denote like ant figures of the-drawings.

1 designates the staff of an umbrella, and 2 is the ordinary notch orcrown-piece; The ribs 3 are pivoted to the notch or crown-piece, andthey are operatively connected by the stretchers to the slidabl'e runner4. All these parts may be of any preferred construction known to thoseskilled in the art. 7

According to my invention the cover 5 to the umbrella or parasolisattached to the outer ends of the ribs 3 in the ordinary way, but themiddle part of the cover is cut away and attached to the ribs, as at6,'for some distance away from the notch or crown-piece 2, therebyleaving an opening or space 7 in the central partof the cover andaroundthe stait 1, through which opening or space the air is free tocirculate. To close this ventilating opening or space against theadmission of the sun and rain to the umbrella, I provide the ventilator8, which is attached to the staff ata point above the notch 2 and isoperatively connected with the ribs for opening and closing therewith. I

This ventilator device embodies the auxiliary notch or crown-piece 9,which is rigidly fastened to the protruding part of thestait 1 at asuitable distance above the rib-notch 2, and to this auxiliary notch isconnected a series of radial foldable arms 10, the inner ends ofwhich'are pivoted, as at 11, to said auxiliary notch. The arms or ribsof the ventilator are designed to lie above the ribs 3 in the samevertical plane therewith, and

drawn across the same, so as to overlapbne corresponding parts in eachof the'several these arms 10 are operatively connected with another attheir adjacent edges, and thereby close the space between the ventilatorand" the umbrella-cover to exclude driving rain from entering theumbrella through the ventilator. The links 12 are pivotally attached attheir upper ends to the arms of the .ventilator, while their lower endsare attached in l like manner to the ribs 3, such pivotal connection ofthe links to the ventilator-arms and the umbrella-ribs being indicatedby 14.

The ventilator-arms are inclosed by a cover 15, which closely surroundsthe staff at the point where the arms 10 are attached to the auxiliarynotch 9, and the outer edge of this cover is secured to the extremitiesof the [oldable arms 10.

The space between the ventilator-cover and i the umbrella-cover may inthe event of emergeinshes be closed by a slidable band or bands; but inthe preferred embodiment of the invention as represented by the drawingsI prefer to employ two bands, which may be adj usted independently ofeach other and are arranged on the ofiset links 12'to overlap oneanother at the meeting edges when closed across the space between thecovers to the ventilator and umbrella. The lower band 16 is attached tothe cover 5 or to the lower ends ofthe links l2 at the. points indicatedat 17,

and in the free upper edge of this lower slidable, band is provided aholding-elastic 18, which is adapted to closely hug the links 12 andsustain the band in its open position across said links. The upperslidable band 19 is fastened at its upper edge,to the ventilator-cover15 or the upper ends of the links 12 at the points indicated by thenumeral 20,

and in the lower edge of said upper slidable-v band is secured theholding-elastic 21, which also serves to hold the band 19 in itsadjusted position on the links.

The umbrella maybe opened and closed by sliding the runner 4 lengthwiseon the staif to adjust the ribs and stretch ers in a well-known manner.The ventilator-arms are pivotally attached to the auxiliary notch andoperatively connected by the links with the um brella-ribs, whereby theventilator is opened or closed with the ribs. \Vhen the umbrella isopened, the links 12 raise the arms 10 and Spread the cover 15 of theventilator. Normally the slidable band 16 is drawn closely against theumbrella-cover,wl1ile the slidable band 19 is raised against theventilator-cover,

and these bands are maintained in their ad.

3 usted positions by the frictional engagement of the holding-elasticswith the ventilatorlinks 12. A free or unobstructed space is thusprovided through the cover of the umbrella and the ventilator for thecirculation of air through the umbrella. It is not necessary in anordinary rain to close the ventilator-space, because the cover 15 of theventi lator will shed the water upon the umbrellacover; but when therain is blown by the wind with considerable force against the;umbrellait is advisable to close the ventilatorspace in order to prevent therain from being ing in the umbrella-cover. This end is atmined bylifting the band 16 on the links 12 and dnww rng the mtn' si .LJtm'rrwaruly on the links, The c ttcnt of adjustment of the two link.These ofisets thus serve to permit the two bands to overlap one anotherand secure close joints between the bands Without making the latterpresent an unsightly appearance.

The cover 15 and the slidable bands 16 19 maybe made of fabric or anyother suitable material, and the holding-elastics in the slidable bandsmay be of rubber or spring metal.

Slight changes may be made in the form of some of the parts, while theiressential features are retained and the spirit of the inventionembodied. Hence I do not desire to be limited to the precise form of allthe part as shown, reserving the right to vary therefrom.

Having thus described the invention, what I cla'm is 1. The combinationwith a staff, umbrellaribs, and ventilator-arms attached to saidfoldable arms; links pivoted to said arms and to the umbrella-ribs, aslidable band attached to the lower ends of the links and provided withan elastic, and anotheuslidable band attached to the upper ends of thearms and also provided with an elastic, the elastics of said bandsserving to confine the bands in fric-- tional engagement with thefoldable links, substantially as described.

3. The combination with a staff and the ribs of an umbrella or parasol,of the foldable arms carrying the cover, the ofiset links pivoted tosaid arms and ribs, and independently-adjustable bands attached to therespective ends of the links and slidably fitted to and around saidlinks to have their adjacent edges separated by the bends or offsets inthe links when the bands are adjusted to close the space between thearms and ribs, substantially as described.

In testimony that I claim the foregoing as my own I have hereto ailixedmy signature in the presence of two witnesses.

MICHAEL ANGELO EATMAN.
